Have a look on Wemoto, they have Tarozzi stanchions that are excellent quality, at £112.50 they're a better alternative to hunting down second hand ones, that may have hidden damage. I had to replace one recently cos the clown that had the bike before me had put gouges into by hammering down a dust seal he'd covered in insulation tape as a makeshift oil seal. I'd replace both oil & dust seals as well, also I'd keep a note of how much damper oil you get out of both forks, chances are you'll put more back in.
